Conserved signature indels

Conserved signature indels (insertions and deletions) refer to specific sequences of nucleotides or amino acids that are either added or removed from a genomic or protein sequence, respectively, which are found to be conserved across different species. These indels often provide important insights into the evolutionary relationships between organisms or may indicate functional changes in proteins. In molecular biology and bioinformatics, signatures refer to distinctive patterns that can be used to identify specific genes, proteins, or evolutionary lineages.
